Lance Dunbar might have been the future at running back for the Dallas Cowboys, but with a terrible knee injury suffered on Thanksgiving, that future is now in question. Dunbar's injury could end up worse than other knee injuries because of the ligament that was hurt and the associated damage.

With surgery and a long rehab upcoming, Dunbar is going to have a difficult road back to where he was before the injury. B/R's Will Carroll takes a look at what happened and why this injury may be worse than the more common ACL sprain for Dunbar and the Cowboys.
